1.5 Heating (DGi version only)
In hard environmental conditions, with condensation or frost, gases and vapours may not reach
the sensor. The device takes into account this difficulty and keeps its temperature slightly above
that of the ambient atmosphere.
1.6 Technical specifications
Each detector is constructed as follows:
•
A wall-mounted support secured by three screws and including cable gland (M20)
(optional). There are 2 standard entries and an optional one.
•
A stainless steel explosion-proof housing containing:
-
A set of tropicalized electronic cards
-
A display and infrared communication electronic card. Allowing the
communication with the remote control (TLU600)
•
A colour coded cartridge with a label located in the lower part of the detector, a green
one for the toxic gas detectors with electrochemical cell (DGi-TT7-E), a blue one for the
oxygen deficiency gas detectors with electrochemical cell (DGi-TT7-O) and an orange
one for semi-conductor toxic gas detectors (DG-TT7-S)
The cartridge is connected to the detector’s body by an open ring leaving the label visible.
A colored ring enables the identification of the device type at a larger distance.
•
A metallic support cable (optional) connects the wall mounting support and the housing,
which makes the maintenance easier.
